The Roomba 650 and the 770 are equipped with iAdapt Navigation. This is a very smart set of technology that uses built-in sensors to detect obstacles and vacuum around them. It doesn’t matter how your home is set up or what the kids leave lying around, both iRobot vacuums will work their way around objects. Let’s begin with how the Roomba 650 and the 770 are alike.

On that note, you do need to be careful with cables and the vacuums are powerful enough to suck up cords. You also need to take care of liquids, as the sensors won’t detect liquid.

Both of these Roombas have a 3-stage cleaning system. The first stage is agitation, where the brushes loosen up any stubborn dirt and debris. The second stage is brushing and the third stage is suction. Roomba hasn’t supplied any information about the dirt cup capacity. It is recommended to empty the cup after every cycle but that will depend on your home.

Again, Roomba has provided little information about how long the 650 and the 770 take to charge. This might be because once the robot vacuums have finished, they automatically return to the docking station and begin charging.

When the vacuum is charging, an orange light will flash, once it is fully charged, the light will turn green. If the batteries begin to lose charge while it is cleaning, they will automatically return to the docking station, or you can press the ‘dock’ button.

The Roomba 650 and the Roomba 770 are suitable for all floor types. You can use them on carpet, tiles, hardwood, and laminate to name a few. Both machines will automatically adapt to the floor type. We tested both on various different floors and were happy with the results until we tried a black carpet. The sensors on the 650 and the 770 will automatically stop the vacuums as it is programmed to think it is a step. However, they do go over things like doorways.

In terms of cleaning capabilities, we tested the Roomba 650 and the Roomba 770 on short and long animal hair, dried mud, breadcrumbs and cereal and neither machine had an issue with cleaning.

It is really easy to set a schedule with the iRobot vacuums. You can set a day and hour for up to 7 times per week. The buttons are conveniently placed on top and there are LED lights for you to see exactly what you are programming. It couldn’t be easier to set a timer and come home each day to a clean home.

All Roomba iRobots have a 6-month limited warranty and a 1-year limited warranty on parts, excluding the battery.

There are only a few differences between the 650 and the 770, so let’s cover them now.

Robot vacuums are round, with an average diameter of 13.7 inches. The average height is around 3.9 inches and the weight will vary between 7 and 15 pounds.

This is a lightweight robot vacuum at 7.9lbs. It is 13.4 in diameter and 3.6 inches high. It has a sleek black design with clearly labeled buttons.

Roomba 770

It weighs in at the higher end of the average at 13.2lbs. It is 13.9 in diameter and 3.4 inches high. Being slightly lower, there is more probability it will fit under your furniture. The buttons aren’t clear until the LED lights come on but we feel this adds to the design.

The winner is – The Roomba 770

Roomba 650 vs 770: Cleaning ability

As we mentioned before, you want a robot vacuum that is able to clean various floor types without the sensors causing it to stop. You especially want it to be effective on more than just dirt and dust.

It has 3-stage cleaning and automatically adjusts to different floors.

Amazing value for money at the lower end of the average price and significantly cheaper than the 650.

Pros and Cons

Before our final verdict, we will finish up with some pros and cons.

Roomba 650

Pros:

  • The battery lasts a good amount of time and will be able to run for at least 45 minutes
  • A very clever navigation system that won’t allow the robot vacuum to get stuck
  • The side cleaning brushes are very effective at cleaning corners
  • Things like bed sheets or material sofa flaps won’t affect the sensors, so it will still clean under the furniture

Cons:

  • It sometimes has issues attaching itself back to the dock, even pushing the dock into a corner making it impossible

Roomba 770

Pros:

  • All of the above mentioned for the 650
  • Works excellently on pet hair and under furniture, you will notice cleaner floors and better hygiene for little ones crawling around
  • Super simple to set up, you won’t need any instructions
  • Great life span and customer service

Cons:

  • It’s a little bit noisy

The Final Verdict

I don’t think we have ever had such a clear winner. Today, we have definitely chosen the Roomba 770 and we can see no justification for spending nearly more than $200 extra for the 650.

The Roomba 770 works brilliantly on all floor types and is particularly beneficial for those who have pets or children. You can set it to clean at a certain time each day or just once or twice a week, depending on what your home needs.

The iAdjust navigation system allows the vacuum robot to work around chair and table legs without getting itself stuck, so you know you can set the cycle for when you are not at home. It easily switches from hard floors to carpets and rugs, working effectively on both. The only downside is that it won’t work on black carpets. Having said that, it is a design flaw and not specific to the 770.

Being just 3.4” high, it is a tad slimmer than the 650. 0.2” may not seem like a lot but it might make a huge difference to someone whose sofa is lower to the floor. We noticed no difference in the cleaning abilities except how clever the 770 was when hunting out the extra dirty spots.

We also preferred the simple design of the 770. They are both black but the 770 has more LED lights, giving it a slightly more modern feel.

The only feature where the 650 could take the advantage is the weight. The 770 is over 5lbs heavier than the 650. But really, this didn’t bother us as we weren’t actually vacuuming. We decided that we would rather carry a little extra weight upstairs than pay out the extra money. In fact, you can almost buy two Roomba 770s for the price of one Roomba 650, and have one for upstairs and downstairs!
